human history

University of Wyoming

A UW professor has co-authored a study that shows a nearly two-million-year-old grinding tool might have actually been used as a weapon.

For years, scientists  have believed round stones, called spheroids, were used by early humans to grind and shape other objects. Spheroids have been found in archaeological sites in South Africa and elsewhere. Archaeologists believe they date back as far as the Early Stone Age, nearly two million years ago.
